Definitions

  • the present invention relates to an electric brake mechanism for heavy vehicles, which can be applied to trucks to be used as a means of retention of this type of vehicle when descending slopes and can replace the normal brake of the vehicle thus preventing overheating and the non-use of said conventional brake.
  • the magnetic force to be applied to the discs or flywheels is originated by magnetic coils which are mounted telescopically on a nucleus, closing this through a pole plate, in such a way that all the whole remains mounted on a support plate, carrying so many polar plates and, consequently, magnetic cores as it becomes necessary.
  • the air circulation through the interior of the assembly is zero, and we give even me the case where the external or flying disc to which we must apply the magnetic forces originating from the cited set, incorporates wings which aim to produce ventilation, even if they do not act as a fan, and they try to create a vacuum inside the box which forms the support plate, and this results in a retention force which means that the truck, while it is operating normally and the electric brake is not applied, consumes enough fuel, since we are creating a vacuum in a closed box and without any air circulation, and this vacuum logically absorbed a quantity of energy which must be supplied by the engine of the vehicle and consequently lose it as yield born from it.
  • the electric brake mechanism proposed by the invention was designed to solve these problems with full satisfaction, based for this on the same operating principles as that which corresponds to the utility model cited 275.521 of the same applicant, whenever '' by presenting a series of innovations with which any type of failure which occurs in the whole of the brake will not require that it be disassembled in relation to the axes of the vehicle, but by simply unscrewing covers, it is possible to access the entire internal mechanism, that is to say, where the crowns are provided, as well as the pinions and other elements. It is therefore not necessary to carry out the disassembly, with the consequent saving of time, economic costs, etc.
  • the mechanism itself presents what can be considered as lateral faces, that is to say, those which are perpendicular to the front faces where the bearings are mounted, totally open by means of large orifices, and on these we have targeted respective circular parts which are extended by one of their faces in the corresponding neck for mounting the magnetic masses, while in the interior or opposite face, extensions have been provided with the shape two arms which have a parallel relationship between them and end in two cylinders or cylindrical parts aligned axially and in transverse direction with respect to the longitudinal axis, so that between each pair of cylindrical bodies or rings it remains in place piece to which the respective pinion meshes.
  • the assembly or magnetic masses to activate the cited electric brake, or another type of brake it has a very simple structure mainly thanks to the particular configuration of the support plate of the magnetic assembly, that is to say, the magnetic coils with their corresponding cores for mounting them. this.
  • This original support plate has a concentric and cylindrical neck of a considerable diameter, through which the assembly will be mounted to the general and static carcass of what forms the electric brake of the vehicle, while in the crown determined between said nucleus and the peripheral edge of the plate of which we are talking, a plurality of boxes have been provided corresponding to one of the faces, boxes which are circular and in which are housed the corresponding cores on which the magnetic coils are mounted, and these close with the respective pole plate.
  • the mechanism forming the electric brake object of the invention which comprises a carcass (1) of essentially cylindrical configuration and which has two opposite mouths (2) on which mounts the respective tubular sleeves (3) in which we precisely housed the bearings (4) on which we mounted the respective vehicle wheels. That is to say, the ends of the tubular sleeves (3) form the mounting means of each axis and the bearings (4) determine the transmission means for the rotation of these wheels.
  • the carcass (1) also has two large mouths (5) with a large diameter, as can be seen in Figure 1 itself, to each of which is added a piece of circular configuration (6), all with screws , so that these parts (6) are extended by its face considered as an outer face in a neck (7), while by its inner face they are extended by arms (8) in parallel relation to each other and end in respective rings or cylindrical portions (9) which form corresponding supports, as will be described later.
  • the pinions mentioned (12) form part of an axis (13), to which the corresponding magnetic disc (14) is coupled which opposes, according to the parallel plane, the magnetic mass mounted on each outer neck (7) of the parts (6), all this in collaboration with a crown (15), the carcass (16), the rings (17), the ball bearings (18), etc., as can be seen in the figure with clarity.
  • the magnetic masses or assemblies have been mounted, which are formed from a support plate (21), of circular configuration and of small size, which has a large concentric orifice (22) from which a neck (23) is derived with orifices (24) for mounting the same on the cited neck (7) of the electric brake.
  • This plate (21) has, in one of its faces, a plurality of grooves or boxes (25) of small depth and circular outline, so that in each of these boxes a core (26) has been mounted on which in turn showed a magnetic coil (27) which is closed with a pole plate (28).
  • all the housings (25) will be supplied from the corresponding assembly forming the core (26), the magnetic coil (27) and the pole or closing plate (28), forming with the own plate ( 21) the magnetic assembly which will activate or act on the own brake disc or flywheel (14).
  • the plate (21) has a peripheral groove (29), while between the recess or boxes (25) there are provided reinforcing nerves (30) as well as pass-through orifices (31), with an inner end rounded bevel (32), as seen in Figure 3.
  • flywheel (14) coupled to the corresponding axis (13) of the braking mechanism, flywheel (14) provided by its rear part of a front (34) which is the one which remains precisely opposite to the plates polar or closing (28), so that when magnetism occurs, said front (33) is the one that will produce the braking of the flat or even flywheel (14) which, as it is united to the corresponding axis of the braking mechanism , will brake the wheels.
  • the mechanism was mounted on the axes corresponding to the non-driving wheels of heavy vehicles, such as large tonnage trucks, so that these wheels will mount on the transmission bearings (4) and consequently on the sleeves. (3), precisely fixed to the general carcass (1) of the mechanism, allowing the rotation of said wheels as a consequence of the gears originating between the pinions (12) and the crowns (10).
